Free shipping is not working
There are 2 methods for activating free shipping.
1. Use field "Shipping Fee per country". Scroll right if the "Free shipping from" field is not visible.
If this field is empty, then free shipping is disabled for the specified country.
If this field contains "0" then free shipping starts from zero cart subtotal (in other words shipping is always free for the specified shipping method and country
If this field contains positive number, then free shipping starts from the cart subtotal (excluding VAT) that is entered into this field -> for the specified shipping method and country
2. Use field "Shipping is free if the cart contains a product that belongs to selected shipping classes"
If cart contains at least one product that has a shipping class defined in this setting then the shipping is free for the specified shipping method. Destination country does not play any role here.
